The advantage of such an arrangeof the lumps of coal,&c.andis made of such ment as the foregoing, both in respect to the manufacture of the retorts, as well as to the preservation of thejoint, will be evident, if it be considered that were the east-iron bend bolted to the fiange of the retort the latter being inclined would necessarily present an oblique angle. According to this improved arrangement, each bend is formed with a rib or tiange (l, as shown, forming a sole-piece, which is supported upon piers c in the setting or otherwise, so that all strain upon thejoint is prevented, and thejoints are consequently more easily made and keptin `good condition. The charging-mouths l), as also the retorts 0L themselves, are suitably isolated from the setting, in order to avoid the effects of expansion and contraction.

Having fully described our improvements and explained their advantages, what we desire to claim `and secure by Letters Patent of the United States as our invention is- 1. A gas-retort bench provided with gas-retorts arranged at the angle of repose for the material treated, said inclined retorts being contracted at their ends, substantially as and for the purpose described.

2. A gas-retort bench provided with gas-retorts arranged at the angle of repose for the material treated, said inclined retorts being substantially sem ieircular in cross-section and contracted at their ends, substantially as and for the purpose described.

El. A gas-retort bench provided with gas-retorts arranged at the angle of repose for the material treated, said inclined retorts being substantially semicircular in cross-sectionand contracted at their upper ends for the purpose described, in combination with chargingchutes, the chargingnnouths of the chutes being constructed to lit upon the contracted mouths oi' the retorts outside of the setting;

il. A gas-retort bench provided with gas-retorts arranged at the angle of repose for the material treated, said inclined retorts being contracted at their upper ends for the purpose described, in co mbinaton with chargingchutes, said chutes having their mouths constructed to tit upon the contracted ends of said retorts and provided with sole-pieces and supports for said sole-pieces.

5. A gas-retort bench provided with gas-retorts arranged at the angle of repose for the material treated, said inclined retorts being contracted at theirupper ends for the purpose described, in combination with chargingchutes, said chutes having their mouths provided with sockets constructed to fit over the ends of the retorts, and a suitable packing (preferably of sand) between the sockets and retort ends.

Y(i.V A gas-retort bench provided with gas-retorts arranged at the angle of repose for the materials treated, said inclined retorts bein g contracted at their upper ends, in combination with charging-chutes constructed to fit upon the contracted ends of the inclined retorts, the planes of the joints being at right angles to the longitudinal axes of the rctorts, substantially as described.

7. A gas-retort bench provided with gas-retorts arrangedat the angle of repose for the material treated and contracted at their upper charging ends, whereby the entering coal will arrange itself in layers parallel to the tioors ot the retorts, but separated from the tops of the retorts by an increased gas-space, and whereby clogging is prevented, substantially as described.

In testimony whereof we have hereunto set our hands and affixed our seals, this 5th day of November, 1890, in the presence ot the two subscribing witnesses.
